OpenSCETool is a clone of scetool under an open source license.

scetool was reverse engineered and analized to produce this program, and copied his behaivour.


  • The instalation is the same of the scetool.
  • You should put your keys inside the data directory along with the vsh_curves & ldr_curves Your idps and actdat should be inside the data directory too.
  • The rap files should go inside the raps directory (at the same level of data directory).
  • The rif files should go inside the rifs directory (at the same level of data directory).
  • You can put klics.txt in the data directory and it will automatically find the klicensee by looking up the content_id.

If you wish, you can set the PS3 environment variable to point to the data directory (your raps & rifs should go in the rap and rif directory).


The usage is exactly the same of the original SCETool, so if you know how to use it.
You know how to use this tool.

The new options available are "-p" to patch the ELF the same way FixELF.exe does. Also, if klics.txt is available, it can automatically choose the klicensee.

What was tested to be working fine

As this is the result of reverse engineering, there might be some errors here and there. This is what I have tested. If you have some problems, or incompatibilities please contact me.
